DESCRIPTION

DIGITAL C++ for DIGITAL UNIX® Systems (formerly DEC C++ for DIGITAL UNIX Systems) offers a complete C++ development environment based on a robust implementation of the Final Draft International ANSI C++ Standard (FDIS). DIGITAL C++ used along with the Developers' Toolkit for DIGITAL UNIX and DEC FUSE offers application developers a complete C++ development environment.

DIGITAL C++ includes:

• The native DIGITAL C++ compiler, which implements the draft ANSI C++ standard. DIGITAL C++ includes support for automatic instantiation of templates, pre-compiled headers, and C++ exception handling. DIGITAL C++ for DIGITAL UNIX Systems generates optimized object code without employing an intermediate translation to C.
• The highly optimizing, reliable Alpha code generator for speed of generated code.
• The C++ Standard Library, including the string library, numeric_limits, auto_ptr, standard exception classes, complex math library, and the Standard Template Library (STL). Portions of the C++ Standard Library have been implemented using source licensed from and copyrighted by Rogue Wave Software, Inc.
• DEC C++ Class Library, containing the following packages: iostream, complex, generic, Messages, Objection, Stopwatch, String, task, and vector. If you are using DIGITAL UNIX Version 4.0 or later, the Class Library is threadsafe and also contains a Mutex package.
• Features to facilitate porting to DIGITAL C++ from other C++ implementations. The -cfront option relaxes error checking for better compatibility with C++ compilers based on the AT&T "cfront" translator. The -ms option provides better compatibility with Microsoft's Visual C++ (TM).
• A name demangler, that enables other tools (besides the compiler and debugger) to present demangled names to the user.

Application developers using DIGITAL C++ are required to purchase a license for the Developers' Toolkit for DIGITAL UNIX. This product provides a set of UNIX development tools that include: a symbolic source-level debugger (Ladebug), ATOM based performance and analysis tools, program analysis tools (profiling and performance analysis), two ANSI conformant C Compilers (including DEC C for DIGITAL UNIX), reordering tools (cord, feedback, and runcord), and the Porting Assistant, which aids in porting to DIGITAL UNIX from other UNIX platforms and from OpenVMS. For further information on these products, please see SPD 44.36.

The Ladebug debugger provides basic debugging capabilities as well as specific support for the C++ language, including function name and operator overloading, C++ scoping, templates, C++ exception handling, multiple inheritance, virtual base classes, and virtual functions. Both window-based and dbx-style command-line interfaces are provided. C++ debugging on DIGITAL UNIX is not supported by dbx, only by Ladebug.

Application developers interested in an integrated, graphical, GUI-based, extensible development environment may be interested in purchasing licenses for DEC FUSE and the DEC FUSE C++ Support option. For more information, please see SPD 44.71.

For more information on the Developers' Toolkit, C Developers' Extensions and DEC FUSE, please see the Optional Software section below.

DIGITAL C++ supports the DIGITAL UNIX features of shared libraries and 64-bit computing.

The DIGITAL C++ documentation provides comprehensive reference and usage information for all product components. Online reference pages (man pages) are provided with the software, and browser-based (html) documents are provided on the Layered Products Documentation CD-ROM for the following manuals: Using DIGITAL C++ on DIGITAL UNIX Systems, DIGITAL C++ Installation Guide for DIGITAL UNIX Systems, and the DEC C++ Class Library Reference Manual. Hardcopy documentation is available by ordering the separate software documentation kit. The hardcopy documentation kit also includes a copy of an authoritative book on C++, The C++ Programming Language, 3rd Edition, by Bjarne Stroustrup.

Run-Time Library Redistribution:

The DIGITAL C++ kit includes updated Run-Time Library shareable images. Digital grants the user a nonexclusive royalty-free worldwide right to reproduce and distribute the executable version of the Run-Time Library ("the RTL's") provided that the user:

• distributes the RTL's only in conjunction with and as a part of the users's software application product which is designed to operate in the DIGITAL UNIX environment;
• does not use Digital's name, logo, or trademarks to market the user's software application product;
• includes Digital's copyright notice for DIGITAL C++ on the user's product disk label and/or on the title page of the documentation for the software application product; and
• agrees to indemnify, hold harmless, and defend Digital from and against any claims or lawsuits, including attorney's fees, that arise or result from the use or distribution of the software application product. Except as expressly provided herein, Digital grants no implied or express license under any of its patents, copyrights, trade secrets, trademarks, or any license or other proprietary interests and rights.

For DIGITAL UNIX systems, the RTL images are designated as:

• libcomplex.a, libcomplex.so,
• libcxx.a, libcxx.so, CXXREDIST600V01.tar
• libcxxstd.a,
• libcxxstd_oldcxx.a,
• _main.o,
• libtask.a, libtask.so,
• cxxl.cat, cxxl_messages.cat

Refer to the DIGITAL C++ Version 6.0 Release Notes for details on how to redistribute the RTL images provided with this DIGITAL C++ kit.

HARDWARE REQUIREMENTS

Any Alpha system that is capable of running DIGITAL UNIX Version 4.0.

Disk Space Requirements

Disk space required for installation:

	On DIGITAL UNIX V4.0
Root file system:	/ 0 MB
Other file systems:	/usr 40.00 MB /tmp 40.00 MB /var 0.00 MB

Disk space required for use (permanent):

	On DIGITAL UNIX V4.0
Root file system:	/ 0 MB
Other file systems:	/usr 40.00 MB /var 0.00 MB

These counts refer to the disk space required on the system disk. The sizes are approximate; actual sizes may vary depending on the user's system environment, configuration, and software options.

SOFTWARE REQUIREMENTS

• DIGITAL UNIX Operating System Version 4.0
• DIGITAL UNIX Developers' Toolkit, Version 4.0

A license for the Developers' Toolkit is required. It is through this product that application developers gain access to Ladebug, a symbolic source-level debugger, and other useful development tools.

For more information on the Developers' Toolkit, please see SPD 44.36.

OPTIONAL SOFTWARE REQUIREMENTS

DEC FUSE and the DEC FUSE C++ Support option provide an integrated, graphical, GUI-based, extensible software development environment for C, C++, and Fortran application development. These tools include special support for C++, such as C++ class browsing, online tutorial, hypertext-based help, code-management tools, and more. Refer to the DEC FUSE for DIGITAL UNIX Software Product Description (SPD 44.71).

This release of DIGITAL C++ includes a version of the Ladebug debugger and debugger graphical user interface. This debugger can be invoked through the graphical user interface that is provided.

In summary, optional software products are:

• DEC FUSE for DIGITAL UNIX, and
• DEC FUSE C++ Support for DIGITAL UNIX

GROWTH CONSIDERATIONS

The minimum hardware/software requirements for any future version of this product may be different from the requirements for the current version. A version update represents a complete distribution media replacement for the previous release of DIGITAL C++ binaries. Product changes and functional enhancements in a version update may require the recompilation and relinking of all modules in an application built with a prior version of DIGITAL C++ to provide for proper operation with the new release of DIGITAL C++.

DISTRIBUTION MEDIA

This product is available on the DIGITAL CD-ROM Software Library for DIGITAL UNIX (QA-054AA-H8) or a CD-ROM containing only the DIGITAL C++ for DIGITAL UNIX (QA-MTRAA-H8). Documentation in hardcopy format can be ordered separately.
